Minidisc was extremely popular outside of the US. Europe/Japan/UK have a large population of people walking, cycling and taking public transport. CDs were bulky, minidiscs were not. In the US you were putting CD-Rs into your car's CD player and going from your driveway to the office. We weren't so the smaller, more convenient device won out.
And of course, when you get your information from commercial sources with a vested interest in capitalism, they are only going to be interested in how many copies of pre-pressed albums are sold and that's not where minidisc found its niche.
Naturally it died off when MP3 players got good because solid state is better than moving parts and in the case of the ipod even moving parts are fine when the software is itunes and not fucking sonicstage.
